What are you using as a pickup?

ear bud headphone with back towards magnet.... on one channel in the pic.  plugged close so as not to pick up sound.

previously tried a mic condensor, not any better.

previously tried bare end wires too, very close together.....  seemed to work better. 

tried a ceramic magnet for trigger, then tried rare earth magnets which are the ones in the pics.  ceramic was better.  want to try an iron magnet, but don't have a good one to use, need to get one.
